It is possible to learn it from a book on your own. I recommend The Feeling Good Handbook by David D. Burns. https://www.amazon.com/Feeling-Good-Handbook-David-Burns/dp/...

This is the book my therapist had me read as part of my “homework” between sessions.

While this is completely anecdotal, it’s helped a number of people I’ve recommended it to and they have recommended it to others, who also have been helped. Learning what emotions are, what they mean, and how to recognize them is empowering.
